Description

This dataset contains the results of multi proxy analyses done on the 20 to 9 kyr cal BP section of a lake sediment core taken from Kokad Mire, E Hungary (47°24’10” N, 21°55’43” E; 112 m a.s.l.). Sediment description, pollen, microcharcoal and major element analyis results are included in the dataset. In addition, input files for quantitative climate reconstruction and output files for biomisation and summer (June-July-August) mean temperature reconstruction are provided with relevant R scripts. The aim of the study was to reconstruct vegetation change, soil development and provide quantitative climate reconstruction for the last glacial termination period for E Hungary and study the early expansion of temperate broadleaved trees (mainly Ulmus and Corylus) in the lowland of E Hungary. Our results suggest that warming was most intensive after Heinrich event 1, around 16,200 cal yr BP, the late glacial climate fluctuation is weakly expressed, the Younger Dryas (GS-1) do not show significant decrease in summer mean temperatures, and hazel shrubs (Corylus) expand in the area at that time confirming that this contintal area was wekly affected by this climate perturbation. The study was published in Quaternary Science Reviews.
